Subject: [PATCH net-next 1/2] ynl: rename array-nest to indexed-array
Date: Tue, 26 Mar 2024 14:37:27 +0800 [thread overview]
Message-ID: <20240326063728.2369353-2-liuhangbin@gmail.com> (raw)
In-Reply-To: <20240326063728.2369353-1-liuhangbin@gmail.com>
Some implementations, like bonding, has nest array with same attr type.
To support all kinds of entries under one nest array. As disscussed[1],
let's rename array-nest to indexed-array, and assuming the value is
a nest by passing the type via sub-type.
